OPINION OF THE COURT
These consolidated appeals are brought by six co-defendants from judgments of conviction and sentence on charges arising from a conspiracy to distribute narcotics. Appellants Giacomo Di Norscio, Gerald Cohen, Gerald Deluca, John Sinico, Anthony Truglia and Vincent Di Pasquale, assert several and various contentions of error in the district court’s conduct of their trial and imposition of sentence. They assert, inter alia, that the district court erred by refusing to grant a motion for an evidentia-ry hearing to determine whether the government had impermissibly utilized its peremptory challenges during voir dire to exclude a cognizable ethnic group; that the district court erred by refusing to grant a motion for recusal; that the district court erred by its imposition of an enhanced sentence pursuant to the federal statute that provides for increased penalties for persons convicted of an offense committed while on bail for a separate offense; and finally, that the district court erred by refusing to dismiss the indictment because the charging grand jury did not fairly represent a cross-section of the community.
I.
Background
Appellants were charged, in a six-count indictment returned in June 1986, with participation in a conspiracy to distribute cocaine between several states during the period between September 1985 and June 1986. Specifically, the indictment alleged that the appellants, together with five co-defendants
The trial of these charges commenced in September 1986 and resulted in the conviction of each appellant for participation in the conspiracy and for possession with the intent to distribute cocaine in violation of 21 U.S.C. § 846 (1982).
Pursuant to these verdicts, the district court sentenced Di Norscio to two concurrent twenty-five year prison terms, a six year special parole term, and a $5,000 fine. It also imposed a consecutive five year term pursuant to 18 U.S.C. § 3147 (Supp. IV 1986) (“§ 3147”).
Following the entry of judgments of convictions and sentences, the appellants timely filed notices of appeal alleging error in the conduct of their trial. They assert: (1) that the government improperly exercised its peremptory challenges to exclude Italian-Americans from the petit jury in violation of Batson v. Kentucky,
II.
Exclusion of Italian-Americans From the Petit Jury
Di Norscio contends that, during the selection of the jury, the government exercised five peremptory challenges against venire persons with Italian surnames for the purpose of excluding Italian-Americans from the jury. Di Norscio argues that the government’s use of peremptory challenges in that manner violated his right to equal protection, as set forth in Batson v. Kentucky,
Immediately following the jury selection, the district court denied Di Norscio’s application for a Batson hearing. It concluded that the Batson rule is explicitly limited to racial discrimination against blacks and, thus, did not extend to Italian-Americans. United States v. Di Norscio, et al., No. 86-223, Trans, of Proceedings (Opinion) at 271 (D.N.J. Sept. 11, 1986), reprinted in Appellants’ App. at 271. Significantly, however, it found regarding two of the challenged jurors, that permissible grounds for exclusion existed, and concluded that even if it read Batson to extend beyond black Americans, Di Norscio had not made the requisite factual showing of the cogniz-ability of the group that he alleges to have been excluded, or that any group was actually excluded. The district court stated its finding that “[Di Norscio’s] application [for a Batson hearing] is bottomed on nothing —on utterly nothing either factual or legal.” Id. at 274.
We need not consider the correctness of the district court’s determination that the rule of Batson is not applicable to cognizable racial or ethnic groups other than black Americans under any circumstances because we conclude that the district court’s decision not to exercise its discretion and order a Batson hearing — on the facts of this case — did not constitute reversible error.
Under Batson, to establish a prima facie case of purposeful discrimination in the selection of the petit jury, a
defendant must first show that he [or she] is a member of a cognizable racial group, Castaneda v. Partida, . . . [430 U.S.] at 494 [97 S.Ct. at 1280 ], and that the prosecutor has exercised peremptory challenges to remove from the venire members of the defendant’s race. Second, the defendant is entitled to rely on the fact, as to which there can be no dispute, that peremptory challenges constitute a jury selection practice that permits “those to discriminate who are of a mind to discriminate.” Avery v. Georgia, 345 U.S. [559] at 562 [73 S.Ct. 891 , at 892,97 L.Ed. 1244 (1953)]. Finally, the defendant must show that these facts and any other relevant circumstances raise an inference that the prosecutor used that practice to exclude the ve-nire[persons] from the petit jury on account of their race.
Batson,
[t]he defendant initially must show that he is a member of a racial group capable of being singled out for differential treatment ... a defendant may then make a prima facie case by proving that in the particular jurisdiction members of his race have not been summoned for jury service over an extended period of time.
Id. at 94,
In our evaluation of factors that must be shown in order to demonstrate the cogniza-bility of a racial or ethnic group, we take some guidance from a decision of the Court of Appeals for the First Circuit. In United States v. Sgro,
[t]he proponent must prove that (1) the group must be definable and limited by some clearly identifiable factor, (2) a common thread of attitudes, ideas or experiences must run through the group, and (3) there must exist a community of interests among the members, such that the group’s interests cannot be adequately represented if the group is excluded from the jury selection process.
Sgro,
Moreover, Di Norscio has not demonstrated that persons with Italian surnames —even if they do not share Italian descent —are themselves an identifiable ethnic group that shares common backgrounds and ideas linked to a single culture and group loyalties, or that there exists among them a community of interests “such that the group’s interests cannot be adequately represented if the group is excluded from the jury selection process.” Sgro,
III.
Denial of the Motion for Recusal
At the time the indictment underlying this appeal was returned, Di Norscio
Judge Barry denied all defense motions to recuse, on the grounds that: (1) the conspiracy charged in the case before her and the conspiracy charged in the Accettu-ro case were separate conspiracies; (2) she had no previous knowledge of the Di Norscio case and had never been involved in any aspect of the prosecution of this case while she was in the U.S. Attorney’s office and; (3) she had no actual bias against the defendants and no reasonable person would question her impartiality. We review the district court’s decision not to grant the motion for recusal for abuse of discretion, see United States v. Dalfonso,
Di Norscio contends that recusal was necessary because Judge Barry served as a Supervisory Assistant U.S. Attorney in the District of New Jersey through November 1983. Di Norscio argues that recusal was mandated by 28 U.S.C. § 455(b)(3), because the judge “served in governmental employment and in such capacity participated as counsel, advisor or material witness ... or expressed an opinion concerning the merits of the ... case.” Section 455(b)(3), however, mandates withdrawal only when “the judge is asked to hear the same case in which [he or she] has been of counsel....” In re Grand Jury Investigation,
The district court found that the conspiracy charged in the Accetturo case terminated at the time of the appellants’ indictments in that case in August 1985. It held, therefore, that the conspiracy underlying the indictment in the present case — which alleged acts that succeeded the appellants’ arrests in Accetturo — was separate from the conspiracy underlying the indictment in Accetturo. We are not persuaded that that factual finding was clearly erroneous.
Even if we accepted Di Norscio’s contention that the conspiracy charged in this case arises from the same factual circumstances as the conspiracy charged in Accetturo, however, recusal was not required under § 455(b)(3). Although, as Di Norscio asserts, the United States Attorney is “of counsel” in all criminal prosecutions within his or her district, see e.g., In
Recusal was also not mandated under either § 455(a), § 455(b)(1). Apart from the allegation concerning the trial judge’s prior employment as Assistant U.S. Attorney, Di Norscio presents no evidence of bias, prejudice or improper motive that Judge Barry harbored with regard to Di Norscio’s case. He does not offer evidence to refute the trial judge’s statement that she had “no personal knowledge of any evidentiary facts concerning this case,” Appellants’ App. at 3262-63, nor did he offer any evidence tending to show that “a reasonable [person] knowing all the circumstances would harbor doubts concerning the judge’s impartiality.” Edelstein v. Wilentz,
IV.
Enhancement of Sentence Pursuant to § 3147
We next review the claim that Di Norscio was sentenced illegally under § 3147. Di Norscio claims that § 3147 establishes a criminal offense. He argues that, because he was not indicted, tried and convicted for that offense, he was not properly sentenced under the provision. Alternately, he contends that even if § 3147 is merely a sentence enhancement provision, the sentence that he received under it was nonetheless improper because he was not given adequate notice of the fact that he was subject to the enhanced penalty. Our standard of review of these issues of statutory construction is plenary. See Chrysler Credit Corp. v. First Nat’l Bank and Trust Co.,
A. Section 3147 Does Not Create a Separate Offense
In reaching our conclusion that § 3147 was intended only to enhance the punishments for other offenses, we are
[sjection 3147 is designed to deter those who would pose a risk to community safety by committing another offense when released under the provisions of this title and to punish those who indeed are convicted of another offense. This section enforces the self-evident requirement that any release ordered by the courts include a condition that the defendant not commit another crime while on release. Given the problem of crime committed by those on pretrial release this requirement needs enforcement. Accordingly, this section prescribes a penalty in addition to any sentence ordered for the offense for which the defendant was on release. This additional penalty is a term of imprisonment of at least two years and not more than ten if the offense committed while on release is a felony. If the offense committed while on release is a misdemean- or, this additional penalty is at least 90 days and not more than one year.
See S.Rep. No. 225, 98th Cong., 2d Sess., reprinted in 1984 U.S.Code Cong. & Admin.News 3182, 3217 (emphases added). This passage refers to penalty only and to the fact that that penalty is “additional” to the sentence imposed for the substantive offense for which the defendant has been convicted. It gives no indication that Congress intended to create a separate criminal offense by its enactment of § 3147 and we have found no such intent evident elsewhere in the legislative history.
Our conclusion accords with a decision of the Court of Appeals for the Ninth Circuit in a case involving a claim identical to Di Norscio’s. In United States v. Patterson,
[s]ection 3147 is a sentence enhancement statute which simply mandates an enhanced sentence for someone who commits an offense while released on bail. There is nothing exceptional about the statute, nor is it vague or ambiguous. The language is plain and the meaning is clear.
Patterson,
B. Section 3147 Does Not Require Specific Notice
Di Norscio also claims that he received inadequate notice that he was subject to penalty under § 3147. He did not claim, at his sentencing, that he was unaware that he was subject to this penalty, and raises this claim for the first time on appeal. We find this contention without merit. We do not read the language or the legislative history of § 3147 as mandating explicit notice to a defendant of the possibility for sentence enhancement as a precondition to sentence and, accordingly, we will affirm the district court’s judgment of sentence.
Di Norscio’s argument on this issue relies upon a decision of the Court of Appeals for the Fourth Circuit. In United States v. Cooper,
Cooper noted that the legislative history of § 3142 included particular reference to Congress’s intent that the statute serve to deter recidivism. Consistent with that goal, as Cooper notes, the legislative history of § 3142(h) states that:
[the judicial officer] is ... required to advise the person [released on bail] of the penalties applicable to a violation of the conditions.... The purpose of such advice is solely to impress upon the person the seriousness of failing to appear when required.
S.Rep. No. 225 at 25, reprinted in 1984 U.S.Code Cong. & Admin.News at 3208, see also Cooper,
Cooper interpreted the omission from the passage of legislative history quoted above of a specific reference to § 3147 — in light of the specific references that that passage makes to other provisions of the act — as indicative of Congress’s intent that the notice requirement of 3142(h) serve as a prerequisite to the imposition of an enhanced sentence under § 3147 even though it explicitly does not serve as a bar to punishment for other violations. See Cooper,
V.
Denial of Due Process In The Constitution Of The Grand Jury
Cohen argues that the grand jury that indicted him substantially under
Duren requires that a defendant prove: (1) that the allegedly excluded group is distinctive in the community; (2) that the group’s representation in jury pools is not fair and reasonable in relation to the number of its members in the community; and (3) that this underrepresentation is due to systematic exclusion in the jury selection process. Duren,
Juries in the District of New Jersey are selected pursuant to the guidelines set out in The Plan of Implementation of the United States District Court for the District of New Jersey Pursuant to the Jury Selection and Service Act of 1968, (“The New Jersey Plan”), reprinted in Supplemental Appendix of Appellee (“Supp.App.”) at 87. The District is divided into three divisions, of which the Newark Division is the largest. Potential jurors’ names are randomly selected from voter registration lists and automobile driver registration lists. Id. at 3, reprinted in Supp.App. at 89. The New Jersey Plan then provides for the merging of the names on the voters lists and the drivers lists, to create consolidated lists. Id. at 3-4, reprinted in Supp.App. at 89-90.
The names of potential jurors that will comprise the master wheel are drawn ran
Cohen claims that the Plan systematically excluded the three groups that he has identified by its use of voter and driver lists as the exclusive source of names for the jury wheel and by the improper merging of these two lists of persons. His only factual support for his entire underrepre-sentation claim is an affidavit from a demographer, Dr. James O’Reilly, who compared a sample taken from the 1984 qualified-juror wheel to the adult population of Blacks, Hispanic-Americans and persons without a high school education in the Newark Division and concluded that the groups were substantially underrepresented.
VI.
Conclusion
In accordance with this opinion, we will affirm the judgments of convictions and sentences entered by the district court as to each appellant.
Notes
. Appellants seek relief from their convictions on a host of other grounds as well. On the claim of ineffective assistance of counsel raised by Sinico, we will adhere to this Court’s prior holdings that such claims are not properly interposed on direct appeal, but should be raised in appropriate collateral proceedings. See, e.g., United States v. Gambino,
Appellants contend that the verdict was affected by juror taint, that the district court erred by failing to grant a motion for severance and by improperly denying the request for a jury charges regarding the alleged existence of multiple conspiracies, that the government’s closing summation unfairly prejudiced the jury and that the verdict was contrary to the weight of the evidence. Di Norscio claims that the district court erred by refusing to dismiss the indictment against him for prosecutorial misconduct and that his prosecution violated his double jeopardy rights. He and DeLuca allege that the district court improperly denied them the opportunity to present a complete defense by erroneously excluding evidence, restricting cross-examination and limiting their opening and closing arguments to the jury. DeLuca and Di Pasquale contend that the district court considered improper factors in its determination of sentence and Di Pasquale contends that his prosecution was improper because it violated the government’s “Petite” policy of not prosecuting persons who have previously been prosecuted in a state proceeding for the same acts that are the basis of the federal prosecution. Truglia con
. Pursuant to Fed.R.App.P. 28(i), each appellant has adopted arguments raised by other appellants to the extent that those arguments apply to him. For convenience and clarity, our discussion of the appellants’ contentions makes reference only to one of the named appellants. We have, however, considered the merit of each argument to each appellant whose conviction and sentence is implicated and, in that light, we reach our decision to affirm.
. These individuals: Frank Suppa, Manuel Mon-teiro, Thomas Marino, Dick Pearson and Robert Fisher each pleaded guilty to the charges prior to the commencement of the trial.
. Hawley, (who changed his name to "Jay Richmond”), testified that he was a regular occupant at Di Norscio’s home in Florida and at Truglia’s home in Florida from September through December, 1985. During that time he witnessed cocaine transactions three or four times a week at either Truglia’s home or at Di Norscio’s home and observed DeLuca and Sínico working for Di Norscio and Truglia as "runners” who picked up drugs in Florida for delivery to New Jersey, New York, Rhode Island and Tennessee. Haw-ley also testified that he was often with Di Norscio and Truglia while they counted the proceeds from these drug transactions. See Joint Appendix to the Briefs of Defendants-Appellants ("Appellants’ App.”) at 207-09.
Hamilton testified that he purchased cocaine on a regular basis from Di Norscio and Cohen. Hamilton had been arrested in Tennessee for the sale of cocaine to undercover drug enforcement agents. He testified that the cocaine in his possession in Tennessee at the time of his arrest was part of a shipment that he had received from DiPasquale who had delivered it to him on behalf of Di Norscio from Florida. See Appellants’ App. at 1439-41.
Fisher, who was indicted with the appellants, testified that he too regularly purchased cocaine from Di Norscio and Cohen. He testified that he delivered cocaine payments to DeLuca in New Jersey, and to Di Norscio and Cohen in Florida. He also testified that he had received cocaine from Di Norscio and Cohen for distribution in Rhode Island. See Appellants’ App. at 1067-71, 1168-70.
. Under § 846, it is unlawful for "(a)ny person [to] attempt[ ] or conspire[ ] to commit any offense defined in this subchapter.” 21 U.S.C. § 846 (1982).
Each of the defendants except Di Pasquale was tried by a jury on these counts and convicted pursuant to the jury's verdicts. Di Pasquale entered a plea of guilty to the offenses with which he was charged.
. Section 848(b) provides, in pertinent part, that
[a]ny person who engages in a continuing criminal enterprise [CCE] shall be imprisoned for life and fined ... if—
(1) such person is the principal administrator, organizer, or leader of the enterprise or is*275 one of several such principal administrators, organizers, or leaders!,]
21 U.S.C. § 848(b) (Supp. IV 1986), and the enterprise involves a quantity of drugs or sum of money that exceeds a delineated amount.
Section 848(d) states that
[a] person is involved in a CCE if:
(1) he [or she] violates any [felony] provision of this subchapter or subchapter II of this chapter ... and
(2) such violation is a part of a continuing series of violations of this subchapter or sub-chapter II of this chapter—
(A) ... undertaken by such person in concert with five or more other persons with respect to whom such person occupies a position of organizer, a supervisory position, or any other position of management, and
(B) from which such person obtains substantial income or resources.
21 U.S.C. § 848(d) (Supp. IV 1986).
. Section 841(a)(1) makes it unlawful:
to manufacture, distribute, or dispense, or possess with intent to manufacture, distribute, or dispense, a controlled substance.
21 U.S.C. § 841(a)(1) (1982).
. Section 3147 provides that
[a] person convicted of an offense committed while released under this chapter shall be sentenced, in addition to the sentence prescribed for the offense to—
(1) a term of imprisonment of not less than two years and not more than ten years if the offense is a felony
18 U.S.C. § 3147 (Supp. IV 1986). The statute further provides that the "term of imprisonment imposed under this section shall be consecutive to any other sentence of imprisonment.” Id.
. We note that several federal appellate courts have assumed that Batson has applicability to racial or ethnic groups other than black Americans. See e.g., United States v. Alcantar,
. While Judge Becker agrees with the discussion in this section of the opinion, he would pretermit it in view of his agreement with the district court that the Batson rule is limited to discrimination against members of cognizable racial groups. See Brown v. North Carolina,
. Pursuant to § 455(a), a judge must "disqualify himself [or herself] in any proceeding in which his [or her] impartiality might reasonably be questioned.” 28 U.S.C. § 455(a) (1982). A judge must also disqualify himself or herself where he or she "has a personal bias or prejudice concerning a party, or personal knowledge of disputed evidentiary facts concerning the proceeding.” 28 U.S.C. § 455(b)(1) (1982). Finally, pursuant to § 455(b)(3) a judge is required to disqualify himself or herself if he or she "has served in governmental employment and in such capacity participated as counsel, advisor or material witness concerning the proceeding or expressed an opinion concerning the merits of the particular case in controversy.” 28 U.S.C. § 455(b) (1982).
. The government argues that Di Norscio did not preserve his right to appeal this sentence because he did not comply with the district judge’s request for a written motion after sentencing. Di Norscio orally objected to the § 3147 sentence. He submitted the motion that the judge requested; it was received and filed but was not listed for argument by the clerk because of Di Norscio’s failure to attach a proposed order. Di Norscio then filed this appeal and the motion was never ruled upon.
We treat the motion before the district court as one for reconsideration of the sentence that was not ruled upon by the district court. Di Norscio, however, is not appealing the disposition of that motion. Rather, he challenges the propriety of the sentence itself. "Final judgment in a criminal case means sentence. The sentence is the judgment.” Berman v. United States,
.Cohen also argues that the alleged underrep-resentation violated his equal protection rights. The Fifth Amendment “forbid[s] discrimination that is so unjustifiable as to be violative of due process.” Weinberger v. Wiesenfeld,
. The Jury Selection Act states “that all litigants in Federal courts entitled to trial by jury shall have the right to grand ... juries selected at random from a fair cross section of the community....’’ 28 U.S.C. § 1861 (1982).
. The same prima facie case is required to prove a violation of both the Act and the Sixth Amendment. United States v. Miller,
. In light of our holding that the claim falls on the third Duren ground, we express no finding regarding the sufficiency of the claim on the first and second factors of the Duren test.
. This methodology is consistent with the Jury Selection Act, which explicitly provides that either voter registration lists or lists of actual voters shall serve as a source for the names of prospective jurors and that plans to determine juror lists “shall prescribe some other source or sources of names in addition to voter lists where necessary to foster the policy and protect the rights secured by [this Act].” 28 U.S.C. § 1863(b)(2) (1982).
. Dr. O’Reilly adjusted upwards the Black and Hispanic-American population, based on his assumption of under-counting in the 1980 census. We will accept these adjusted population figures for purposes of this analysis.
